Welcome to songho.ca

This is my personal web site. I started to convert my notes into the web pages since mid 2005. These are mostly fundamental information or tutorials to share with others. I hope you find what you are looking for here. And, I welcome any feedback on the contents and your suggestions.

You do not need to leave your room. Remain sitting at your table and listen. Do not even listen, simply wait, be quiet still and solitary. The world will freely offer itself to you to be unmasked, it has no choice, it will roll in ecstasy at your feet.

- Franz Kafka
